erosion of metal as a result of fluid blasting
(OP)
Hi,
Can anyone point me to references to determine the erosion rate of steel that is being blasted by a fluid spray. I'm trying to determine how thick to make a plate that will be used to contain a leak emanating from a high temp/high pressure source. I'm trying to solve a problem such as: if a 500 degree, 500 psi system began leaking from a 0.125" hole onto a 0.375" plate (12" away); how long before the plate was punctured?
thanks,
Dave

you must get smarter than the software you're using.

This whole thing doesn't sound like a good idea to me.
Ps 500 degrees what? F or C? what fluid?

However I still think the problem will be the hole. With the highest fluid velocities, pressure and temperature there, it will most certainly enlarge, one can only hope not explosively.

Best solution is to shut the system down and fix the leak.

You don't play around with 500 psi x 500 F

dhengr, somedays I wish passwords could fix the leaks I'm dealing with.

Steel piping does not generally fail in a catastrophic manner. It takes time for a corrosion leak to occur. The leak will start with seepage first, and then take considerable time to enlarge to an 0.125" hole. There will be adequate time to observe a leak before the leak starts damaging other equipment.
If you have a 500 degree, 500 psi system leaking from a 0.125" hole, most people would shut the system down because of the cost of the lost energy.
Water jets use 20,000 psi pressure, so you don't need to worry about cutting through steel. 3/16" plate will suffice for some time.

The difficulty I'm having and maybe a few others are that I can't figure out what you're doing or how you can actually safely work in such a scenario. 500F and 50 psi fluid leaking from a pipe is not to be niffed at.
in terms of sleeves here are some designed to be placed around active leaks to reduce pollution etc, but ether way, your outline of conditions is so low as to not cause any significant decrease in wall thickness.
